HARRISBURG – The PA Department of Health is pausing use of the Johnson & Johnson/Janssen COVID-19 vaccine during an investigation into reports of unusual blood clots. The department told COVID-19 vaccine providers to stop administering the single-shot vaccine until at least April 20 “out of an abundance of caution.” They are taking the steps as a precaution until the CDC and FDA have time to review six incidents of rare blood clots that occurred within two weeks of receiving the Johnson & Johnson vaccine. The six cases occurred in women between 18 and 48 who were among the 6.8 million Americans who received it. State health officials suggested the impact on the state’s overall rollout will be small. The majority of Pennsylvanians who have gotten a COVID-19 shot received either the Moderna or Pfizer vaccine, both of which are unaffected by the pause.
